I dl'd FC: C and some other stuff in one night. I only have 1.5mbit adsl. Over a decades old copper network
To be fair, I'm less than 1km from the exchange and the local population is small...so congestion only really happens during the day but mostly when kids finish school. Weekends there's more load but I just stay up later than most people around hereand take naps to compensate.
You'd have a pretty fast connection using fibre though yeah?
